Hardware & Networking

If you want to pursue a career in networking then there are two ways to do it:
1. Do specialization in computer networking by doing PG from IISc, IIT, NIT, etc. After completing PG, you will get a chance to work with networking giants like Cisco, Orange, Juniper, etc. Here you can get a chance to work in their R&D department. (Here you work as a researcher).
2. Another way is that you can enter into this field by obtaining vendor certifications like CCNA, CCNP, CCIE (Cisco track) or JNCIA, JNCIP, JNCIE (Juniper track), etc. By following this certification track, you will be able to design, install, configure and troubleshoot small to the large-sized network. This is also a good choice to enter in the networking field. (Most people follow this).
Now, the choice is yours, whether you want to become a researcher in networking field or to become a network professional.
Both ways are good. Ask yourself and decide which path to follow.

Yes, sure. There are many training institute, which offers ethical hacking courses. If you pursue B.Tech, then doing summer and winter training is very useful and informative for future use. Some training institute are Futurenext technologies, CETPA, netcamp etc. I will advise you to pursue your B.Tech course and in summer vacation of 1 year you can join summer training. Doing summer training has lots of benefits, like the time period of 2 months is utilities in a very good way, you learn something new, you will get certificate at the end of your training, and if you join project based summer training then it helps you to increase the practical knowledge as well as you get 2 certificates ( 1 for completing the training course and other is for your project ), the certificate you get can be use in getting a job and helps you to increase your experience level. There is one government course which is offered by NPTEL, it is very popular and here you can get training for ethical hacking. These courses are conducted by IIT's. The fee is also very much less. But if you are hardworking then only join the course otherwise not. Another suggestion to you is if you go for private training courses then make sure they will provide you hard copy of the certificate and join for 6 weeks course only. For any query please feel free to ask.
